Product Information

ESU428 is a new hardener designed to replace ESU429 for use with ESU420 and ESU421 epoxy primers. With the introduction of the new hardener, corrosion resistance, adhesion to multiple substrates, and product stability have been improved. Steel, aluminum, galvanized, and galvaneal substrates may now be coated. The product mix ratio will remain unchanged.
